The wells were filled
with 100 μL of the extracts, and the plates were incubated at 37 °C
for 24 h, when the diameters of the inhibition zones were measured
using a caliper rule. Results were evaluated according to the following
scale: b16 mm, inactive; 17–19 mm, partially active; 20–25 mm, active;
N25 mm, very active.
